Hi all, BTW It's worth clicking the links to the imgur gifs ;) first: thx to prikle for the last maintenance on the Mendel90 3D-printer, I noticed you cleaned all the dust and everything and probably did other maintenance like lubricating, etc... Hey, give us a little heads-up on what you did, It will be greatly appreciated. This is a community effort and don't be shy, if you contribute. Tips fedora http://i.imgur.com/DtkDzyY.gif I apologize for suspecting you changed the firmware, you were the last one reported to have done something... my bad, please take my apologies. I owe you a Mate or something! About the firmware: If there is a need for different parameters, please *ALWAYS* inform everyone else, and don't just upload a different firmware and leave it after you are done. "Works for me" attitude isn't nice in a shared environment: http://i.imgur.com/nd2caJ4.jpg I believe the reason why I sometimes find a different firmware with wrong parameters is the bit-rate. Problem is: if you upload a different firmware the PID-regulated heatbed will be changed to "bang-bang" mode (it is as bad as it sounds), support for real arcs will go and the z-height will most like likely be wrong as well as the Extruder-Steps-per-mm parameter which I have calibrated some time ago. If we don't agree to a common firmware it will be a never ending story: http://i.imgur.com/boqq3TN.jpg But there is no need to make it over-complicated: http://i.imgur.com/BKgvFS8.gif I suggest, we leave the firmware as-is, if somebody needs a different bit-rate than 250 kbit/s (I admit it's non-standard), I can change it permanently to 230,4 or 115,2 kbit/s and everyone will use the same setting. Can everyone agree to this? I can. Please vote on: https://metalab.at/wiki/3DPrinter (section Software / prerequisites) until end of march. We will choose the maximum settings supported by everyone http://i.imgur.com/eN9SVBN.gif Love, kisses and nice things for everyone (http://i.imgur.com/WTPY1l1.gif) MiKa PS: The chocolate extruder for our Mendel90 is making progress... Do you want to know more?
